Over the past couple months, I have been doing quite a bit of research in Summit County. You can find the Tubbs' listed several times in local newspapers of the period. Check this site for newspaper searches: https://sites.google.com/site/onlinenewspapersite/Home/usa/c...
Also, the Trails to the Past Summit County site adds more each week as the organization grows: http://www.rootsweb.ancestry.com/~cosummtp/index.html
I live in Summit and can do look ups, if needed.
Have a great day!
